Bodyguards by Day, Lovers by NightEpisode 9

At a high-society party, Selena and Emma were targeted for revenge by an ex-boyfriend and found themselves in danger. Their respective bodyguards, Noah and Carson, worked together to save them, but Noah got injured in the process. Selena then demanded that Emma send Carson to serve at her house for three months as compensation. While at Selena's home, Carson was gradually charmed by Noah's flirtations and decided to break free from the control of Emma's brother, a powerful gangster. However, Carson soon discovered that Noah was actually Selena's brother and the mysterious heir to a wealthy family, and that everything had been a carefully orchestrated love trap set by Noah ever since the night he was saved by Carson ten years ago.
